Description
Die Erfindung betrifft eine Anordnung von Strömungsdämpfern für Turboladermotoren.The The invention relates to an arrangement of flow dampers for turbocharged engines.
Turboladermotoren weisen im Allgemeinen akustische Störungen durch hochfrequente Strömungsgeräusche auf, die durch Unwuchten und geometrischen Verzüge der Schaufeln verursacht werden. Diese Störungen sind als "Turboladerpfeifen" bekannt. Diese lästigen Schallanteile lassen sich wirkungsvoll durch abgestimmte Strömungsdämpfer bei kleinsten Bauräumen reduzieren bzw. ganz vermeiden. Außer dieser akustischen Funktion sind noch anderweitige Belange, z.B. bei der Montage zu berücksichtigen, wobei einfache und sichere Handhabung, Dichtheit sowie automatische Montagemöglichkeiten zu realisieren sind.turbocharged engines generally indicate high-frequency acoustic interference Flow noise, caused by imbalances and geometric distortions of the blades become. These disorders are known as "turbocharger whistles". These annoying sounds can be effectively reduced by matching flow dampers in the smallest installation spaces or completely avoided. Except This acoustic function is still of other concern, e.g. to be considered during assembly whereby simple and safe handling, tightness as well as automatic mounting options to be realized.

Nachteilig dabei ist, dass eine derartige Verbindung über radial abstehende Verbindungsglieder für eine Verbindung mit Druckstutzen von Turboladern ungeeignet ist, da dadurch eine ausreichende Dichtfunktion nicht ohne weiteres gewährleistbar ist. Weiterhin nachteilig ist, dass die beiden Leitungsteile in Einsteckrichtung des ersten Verbindungsteils immer unter maximaler axialer Vorspannung gehalten werden. Dadurch können elastische Teile, beispielsweise Dichtmittel im Laufe des Gebrauchs nachlassen.adversely it is that such a connection via radially projecting links for a connection is unsuitable with pressure port of turbochargers, as a result sufficient sealing function can not be guaranteed without further ado is. Another disadvantage is that the two line parts in Insertion direction of the first connection part always at maximum axial preload can be maintained. This allows elastic parts, for example Deflate the sealant during use.
Aufgabe der vorliegenden Erfindung ist es daher, neben den bekannten akustischen Funktionen bei einfacher und sicherer Handhabung neben automatischen Montagemöglichkeiten auch eine Dichtheit zwischen Strömungsdämpfer und Druckstutzen zu realisieren.task The present invention is therefore, in addition to the known acoustic Functions with simple and safe handling in addition to automatic mounting options also a tightness between flow damper and To realize pressure nozzle.
Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Anspruches 1 dadurch gelöst, dass der Strömungsdämpfer durch Einstecken des Strömungsdämpfers in den Druckstutzen des Turboladers mit diesem zu einer Einheit verbindbar ist, dass der Strömungsdämpfer in seinem Sitz im Druckstutzen entgegen der Einsteckrichtung durch eine zwischen Strömungsdämpfer und Druckstutzen angeordnete elastische Ringfeder unter axialer Vorspannung gehalten wird, und dass die Ringfeder zusätzlich Dichtfunktionen übernimmt.These The object is in connection with the preamble of claim 1 solved by that the flow damper through Inserting the flow damper in the pressure port of the turbocharger with this unit can be connected is that the flow damper in its seat in the discharge nozzle against the insertion direction one between flow damper and Pressure nozzle arranged elastic ring spring under axial bias is held, and that the annular spring additionally assumes sealing functions.
Dadurch, dass der Strömungsdämpfer direkt in den Druckstutzen des Turboladers eingesetzt wird, werden Turbolader und Dämpfer zu einer Einheit verbunden. Dadurch, dass der Strömungsdämpfer entgegen der Einsteckrichtung durch eine zwischen Strömungsdämpfer und Druckstutzen angeordnete elastische Ringfeder unter axialer Vorspannung gehalten wird, wird vorteilhaft erreicht, dass die elastische Ringfeder weniger schnell ermüdet bzw. auch bei nachlassender Elastizität noch ausreichend vorspannt. Etwaige Toleranzen und Temperatur schwankungen etc. wirken sich dabei weniger nachteilig aus. Durch Verwendung einer elastischen Ringfeder zwischen Strömungsdämpfer und Druckstutzen wird zudem eine zusätzliche Dichtfunktion ermöglicht. Radial bzw. seitlich am Strömungsdämpfer angeordnete Verbindungsglieder werden nicht benötigt, so dass eine gute Dichtfunktion bei relativ einfacher Montage und kostengünstigem Aufbau ermöglicht wird.Thereby, that the flow damper directly in The turbocharger's pressure port is used to become a turbocharger and dampers connected to a unit. Because the flow damper opposes the insertion direction by an arranged between the flow damper and discharge nozzle elastic Ring spring is held under axial bias, is advantageous ensures that the elastic ring spring less fatigued or even with decreasing elasticity still sufficiently biased. Any tolerances and temperature fluctuations etc. are less detrimental. By using an elastic ring spring between the flow damper and discharge nozzle is also an additional Sealing function possible. Radially or laterally arranged on the flow damper links are not needed allowing a good sealing function with relatively easy assembly and inexpensive Construction possible becomes.
Gemäß einer bevorzugten Ausführungsform der Erfindung wird der Strömungsdämpfer durch ein Widerlager im Druckstutzen gehalten, das als eine Spannfeder oder ein Spanndeckel oder eine Umbördelung des Druckstutzens ausgeführt ist.According to one preferred embodiment of Invention is the flow damper an abutment held in the discharge nozzle, acting as a tension spring or a clamping cover or a flange of the pressure port is executed.
